How to Deal with Uneven Brake Pad Wear on Carbon Braking Surfaces

Uneven brake pad wear on carbon braking surfaces is a common issue for riders using high-performance wheels. Over time, differences in pressure, alignment, or contamination can cause one pad to wear faster than the other, reducing braking efficiency and potentially damaging the rim.

To address this problem, first inspect the brake pads and rim surface carefully. Look for signs of glazing, embedded debris, or uneven material removal. Cleaning the rim with isopropyl alcohol and a soft cloth can remove contaminants and help restore consistent braking.

Next, check the alignment of the brake caliper. Ensure that the pads contact the rim squarely and that the caliper is centered. Minor adjustments to pad position or caliper mounting bolts can help even out wear.

Brake pad selection also matters. Use pads specifically designed for carbon braking surfaces and replace them if they are excessively worn. Pads designed for aluminum rims can cause uneven wear and reduce braking performance.

Regular maintenance is key. Inspect pads and rim surfaces frequently and clean or replace components as needed. Avoid aggressive braking under wet or contaminated conditions whenever possible, as this accelerates uneven wear.

By carefully monitoring pad condition, maintaining proper alignment, and using the correct pads, riders can extend the life of both brake pads and carbon rims while ensuring consistent braking performance and safety.
